.7 Claims..

This inventionrelates to Venetian blinds, and particularly to side guides for attachment to certain slats of the Venetian blind to. keep vit from swinging when a breeze strikes the blind through an open window.

It has for its objects:

v First, to provide a simple, inexpensive improved side guide construction for Venetian blinds.

Second, to provide such a construction in which a sheet metal socket is provided in -the end of the blind to receive a removable guiding pin which is resiliently held in the end of the slat and is removable from the slat if desired.

Third, to provide such a device which may be used satisfactorily with wooden slats and which will prevent slitting of the slat, and will eliminate unsightly connections between the guiding member and the slat.

Fourth, to provide such a device which may be suitably applied, simply and inexpensively, to metal slats with a minimum of modification oi the slat.

Other objects pertaining to details and econ4 omies of the invention will denitely appear from the description to follow. The invention is defined in the claims. f

A structure embodying the invention is clearly illustrated in the accompanying drawing, in

Fig. 4 is a detail sectional view taken on line '4 4 of Fig. 2.

Fig. 5 is a detail perspective view showing a 40 modiiication of my invention to make it applicable to metallic slats.

Fig. 6 is a detail sectional view through a metal slat and my device applied thereto.

In the drawing I is a Venetian blind having a head bar 2, wooden slats 3 and lift cord d.- Along the window casing at the side of the. blind I provide a track 5 consisting in this instance of a suitable hollow rod having Ia. C-shaped cross section. Riding in this track is ashoe 6 formedto ride between the edges of the c-shaped track. A pin 'l is swiveled in an aperture 8 in the shoe. The pin has a `{reduced portion 9 extending through the aperture and is riveted at Il! to pro'- vlde a sliding loose it.

In the end of the wood slat I provide a slot (CL 15d-41W) ii extending longitudinally thereof and opening at the end of theslatto receive the pin l. A sheet metal member l2 having sides i3 and il embraces the end oi the slat and is provided with an aperture 22 in register with the slot 5 for the passage of the pin i. The members I3 and itl extend along the sides of the slat and completely cover and conceal the slot l I. Prongs I5 are provided on thesemembers to be driven into the wood of the' slat to hold the member 10 l2 in position. g/

The sides i3 and il at the rtions thereof extending over the slot are iormedv as at I6 and Il to provide a socket embracing the pin l, and detenta it are provided in the metal to resili- 15 ently and removably engage an annular ring i9 in the pin. It will be apparent that with this arrangement the end of the slat 3 is reinforced and a sheet metal resilient socket with inter-engaging means to engage complementary means .0 on the pin are provided, and that by moving the slat with the guiding means thereon to the end of the track it is possible to remove the slat and the guiding means.

In Figs. 5 and e i show the application of my 25 invention to an all-metal slat |03. A shoe |ll6 identical with the shoe 6 is provided to ride in the track'such as the track 5. Pin |07 identical in all respects withthe pin l is provided.

Extending longitudinally of the metal slat is a 30 formed groove 20 in which the pin |01 rests.i Struck up from the metal of the slat and extending transversely of the groove is a band 2| to embrace-the side of the pin opposite from the side embraced by the groove 20 so as to 35 form a sheet metal socket in the end ofthe slat |03. A detent H8 is provided to engage the annular ring H3 in the slat.

It will be apparent that with this arrangement a sheet metal socket is vformed in the end 40 ,of the slat |03 to resiliently hold the pin in place, and that there ls-no light visible through the slat at the point of engagement with the pin. Y

yHaving thus described my invention what I 15 'claim as new and desire to secure by Letters Patent is: 1'

1.An end guide construction; for a Venetian blind comprising the combination of a track, a shoe sliding on said track, a pin swlveled on said 50 shevand having an annular groove thereon spaced from the shoefa slat having a longitudinal slot therein opening at the end thereof to receive pin, a sheet metal member fitting over the endo! said slat and having sides em-.iracing and 55 covering the slot, said member having an aperture at the end thereof in registration with the slot for the passage of said pin, the sides of said member being formed ,at the portions thereof adjacent said slot to provide la socket for said pin, and a detent formed in one .of said portions to engage said annular groove on said -pin whereby the pin is resiliently and detachably held in said socket.

2. An end guide construction for a Venetian blind comprising the combination of a track, a shoe sliding on said track, a pin swiveled on said shoe and having an annular groove thereon spaced from the shoe, a slat having a longitudinal slot therein opening at the end thereobto receive said pin, a sheet metal member iltting over the end of said slat and having sides embracing and covering the slot, said member having an aperture at the end thereof in registration with the slot for the passage of said pin, and a detent formed in one of said sides to engage said annular-groove on said pin whereby the pin is resiliently and detachably held in said socket.

3. In an end guide construction for a Venetian blind. the combination of a track, a shoe sliding on said track, a pin swiveled to said shoe and 'having an 4annular groove thereon spaced from said shoe, a sheet metal slat having at its end a longitudinal groove to receive said pin and having a struck-up portion extending across said groove to embrace the other side of said pin resting in blind, the combination of a track, a shoe sliding on said track, a pin swiveled to said shoe and having Van annular groove thereon spaced from said shoe, a sheet metal slat having at its end a longitudinal `groove to receive said pin and a band extending across said groove to embrace the other side of said pin resting in said groove to form a socket therefor, and a detent in the metal formsaid groove to embrace the other side of said pin resting in said groove to form a socket therefor, said pin and said socket having interengaging means whereby said pin is resiliently and detachably held in said socket.

6. In an end guide construction for a Venetian blind, the combination of a track, a shoe sliding on said track, a pin swiveled to said shoe, and a sheet metal slat having at its end a longitudinal groove to receive said pin and a band extending across said groove to embrace the other sideQf said pin resting in said groove to form a'socket therefor, said pin and said socket having interengaging means.

7. In an end guide construction for' a Venetian blind, the combination of a track, a shoe sliding on said track, a pin swiveled to said shoe and having an annular groove thereon, a'slat having a sheet metal socket at the end of and extending longitudinally of the siat, and adetent in the walls of said socket resilientiy engaging the annular groove on said pin.
